[U-Boot] [PATCH 09/15] MPC85xx: Add RMII support for MPC8569MDS

Wed May 20 18:30:37 CEST 2009
This patch supports UCC working at RMII mode on PIB board, fixup fdt blob to
support rmii in kernel. It also changes the name of enable_mpc8569mds_qe_mdio to
enalbe_mpc8569mds_qe_uec which is more accurate.
